   Abstract:  Data from the acoustic surveys of MV SA "Aghulas" and FRV "Walter Herwig ... geostatistical methods. Estimates of mean density (g m-2) of krill and their variances are compared with ... sampling theory. A further high-resolution geostatistical analysis of the MV SA "Aghulas" (ping ... -by-ping) data set of the density of each individual aggregation is also presented. These analyses ...
